Abstract
A data transmission method and apparatus, wherein a first SSB set corresponding to a transmission window and a second SSB set taken as a subset of the first SSB set are provided, and at least one SSB in the second SSB set is transmitted in the transmission window, which may be adapted to cell coverage of different situations, and improve flexibility of resource scheduling.
Claims19
A data transmission apparatus, configured at a network equipment side, the apparatus comprising:
- a transmitter configured to, in a first transmission window, transmit at least one synchronization signal block (SSB) in a second SSB set indicated by a first indication information;
- and
- transmit the first indication information, the first indication information indicating the second SSB set based on corresponding relationships between the SSBs in a first SSB set and a second index,
- wherein the SSBs corresponding to different time-domain positions in the first transmission window, the second SSB set is a subset of the first SSB set, the second index being representative of quasi-colocation relationships between the SSBs in the first SSB set, and the first SSB set comprising two SSBs corresponding to identical values of the second index, the two SSBs corresponding to identical values of the second index being quasi-colocated (QCLed).

A data transmission apparatus, configured at a user equipment side, the apparatus comprising:
- a transceiver configured to receive at least one synchronization signal block (SSB) in a second SSB set indicated by a first indication information in a first transmission window, and
- receive the first indication information, the first indication information indicating the second SSB set based on corresponding relationships between the SSBs in a first SSB set and a second index,
- wherein the SSBs corresponding to different time-domain positions in the first transmission window, the second SSB set is a subset of the first SSB set, the second index being representative of quasi-colocation relationships between the SSBs in the first SSB set, and the first SSB set comprising two SSBs corresponding to identical values of the second index, the two SSBs corresponding to identical values of the second index being quasi-colocated (QCLed).
